TO ALL WHOM IT MAY CONCERN:

Be it known that I, Geenen W. WHITE, of New Haven, in the county of New Haven, and State of Connecticut, have invented a new linproveinent in Shirt-Studs; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters ot'rcference marked thereon, to be afull, clear, and exact description of' the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a perspective View of the hack or inside,

Figure 2 a like view, the-button turned so as to lock the stud in the button-hole, and in Figure 3 a sectional View enlarged.

This invention relates to an improvement in the construction of studs or buttons for similar application, andconsists in the peculiar construction whereby the stud is locked in the button-hole; and in ord-er to the better understanding oi' my invention, as well as to enable others to construct the same, 'I will proceed to la description as illustrated in the accompanying drawings.

A is the hutten or plate formed with a shank, et, (see tig. 3,) projecting 4from the plate A, and to which said shank an elliptical-shaped plate7 ol, is xed, and over the shank and between the plate A and the plate d, and yof nearly the same form and size of the plate d, is arranged-a hanf, thesaid barfformed and arranged so as to be turned upon the shank between the plates A and d, as from the position in fig. '1 to that seen in Hg. 2. In

the inside of the barfis arranged a spring,` as denoted in blue tig. 3, holding the said barfih either of the two positions denoted in black and red in said fig. 3, or as denoted in tig. 2, the said spring bearing upon the sides ofthe square shank a. When the bar is in the position seen in tig. 1, insert the plate l and barfthrough 'the button-hole, then turn the plate A one-quarter around, as .from the positioniin tig. `l to that in Iig. 2; the barf will remain stationary in the hutton-hole while the plates A and ol are turned to the position seen in tig.`2, so 4that the plate d crosses the button-hole, and when desired to remove the stud, reverse the operation. Thus I have produced a stud which may be locked or unlocked without the necessity of touching the mechanism upon the back of the stud.

Having -thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

'.lhe barfin combination with the plates A and c'Z, constructed and arranged -tooperate Veubstantially in the mann-er'helein set forth.
